Numerical calculation and analysis of arc tooth tenon joint

Two cylinders contact problem and plan contact problem were analyzed, and feature of convergence was discussed. Some numerical calculations of an arc tooth tenon joint with three teeth were done. Then, the contact stress with ANSYS was analyzed, and the results of trapezoid tooth and arc tooth tenon joint were compared to find that the latter decreased the contact stress, the third principle stress and von Mises stress. Based on this, some optimizations about the arc tooth tenon joint were done, and the stress was decreased again by optimization.
